John Gill Commentary Leviticus 8:36

"And Aaron and his sons did all the things which Jehovah commanded by Moses." — Leviticus 8:36 (ASV)

So Aaron and his sons did all things which the Lord commanded by the hand of Moses . ] They submitted to have them done to them, and for them, what was done on the first day of their consecration, all the rest of the days; and they kept within the tabernacle all that time as was enjoined them.
